Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning ventilation technology, in particular to a ventilation assembly with variable air supply direction and an air conditioning system. BACKGROUND

[0002] Glass curtain walls have good lighting and light weight, and are thus widely used in modern high-rise office building construction. However, sunlight can easily enter the room through the glass curtain wall, and the glass curtain wall has a large thermal conductivity, so the air temperature in the area close to the glass curtain wall (usually referred to as the outer area) is affected by the outdoor ambient temperature change and sunlight. The office building floor usually adopts a large open layout, with a depth of more than 8m, and the area within 4-6m close to the glass curtain wall is usually referred to as the outer area, and the area away from the glass curtain wall and close to the core tube is referred to as the inner area. The outer area is directly affected by the solar heat gain of the external envelope (glass curtain wall), the temperature difference heat transfer, the radiation heat exchange and the air infiltration; due to the small heat capacity of the glass curtain wall, the change of the outdoor ambient temperature will quickly affect the indoor temperature of the outer area, resulting in obvious temperature fluctuations in the outer area and large variation of air conditioning load; in winter, the heat loss through the glass curtain wall accounts for a high proportion of the heating load, up to 30-50%. The inner area is far away from the external envelope and is mainly affected by the heat generated by personnel, equipment and lighting, etc., and the internal heat generation has a large impact on cooling; since the inner area is not directly affected by the external environment, its load is more stable than that of the outer area, and the variation is small; due to the continuous heat generation of personnel and equipment, the inner area may need to be cooled even in winter. In summary, in winter, the inner area needs to be cooled due to the large heat generation, but the outer area needs to be heated due to the low outdoor temperature environment, and in summer, the outer area has a high temperature and large temperature fluctuations due to the sunlight.

[0003] In order to solve the above problems, office buildings usually adopt a mechanical refrigeration system and a gas heating system to provide air conditioning cold water and air conditioning hot water throughout the year, and each office floor adopts a full-air variable air volume air conditioning system, so a large amount of electricity and gas is consumed, and since the outer area is greatly affected by the external environment, the outer area often delivers a larger air volume, and the inner area delivers a smaller air volume, which causes the problem of excessive fresh air volume and excessive fresh air energy consumption caused by the large air volume supply for cooling in the outer area.

It can be understood that in the office building, the area close to the glass curtain wall is generally referred to as the outer area, and the area far away from the glass curtain wall and close to the core tube is referred to as the inner area. The ventilation assembly comprises a first ventilation air port 1 and a second ventilation air port 5, the first ventilation air port 1 is located in the outer area of the building, and the second ventilation air port 5 is located in the inner area of the building. For example, the first ventilation air port 1 is located on the suspended ceiling of the outer window area of the outer area of the building, and the second ventilation air port 5 is located on the suspended ceiling of the inner area of the building. The air inlet of the first air inlet pipe 2 is communicated with the first ventilation air port 1, the air outlet of the first air outlet pipe 7 is communicated with the first ventilation air port 1, the air inlet of the second air inlet pipe 4 is communicated with the second ventilation air port 5, and the air outlet of the second air outlet pipe 6 is communicated with the second ventilation air port 5.

[0034] Preferably, the first air inlet pipe 2 is provided with a first valve 21, the second air inlet pipe 4 is provided with a second valve 41, the first air outlet pipe 7 is provided with a third valve 71, and the second air outlet pipe 6 is provided with a fourth valve 61; when the first valve 21 and the fourth valve 61 are opened, the third valve 71 and the second valve 41 are closed; when the first valve 21 and the fourth valve 61 are closed, the third valve 71 and the second valve 41 are opened.

[0035] For example, in summer, the controller controls the third valve 71 and the second valve 41 to be closed, and the first valve 21 and the fourth valve 61 to be opened, so that the first air inlet pipe 2, the fan box 3 and the second air outlet pipe 6 are sequentially connected, the air in the outer area of the building enters the ventilation assembly from the first ventilation air inlet 1, is pressurized by the fan, and then enters the inner area of the building from the second ventilation air outlet 5, so that the air with high temperature in the outer area of the building is sent to the inner area of the building, and the air from the outer area is mixed with the air in the inner area (in the embodiment, the outer area refers to the outer area of the building, and the inner area refers to the inner area of the building) to reduce the temperature and then circulate to the outer area, thereby reducing the heat in the outer area, saving the cooling energy consumption of the outer area, balancing the difference in fresh air amount between the air in the outer area and the inner area, and reducing the fresh air supply amount of the air conditioning box. It can be understood that the air conditioning supply air includes fresh air and return air, the fresh air is fresh air introduced from the outdoor, which is used to supplement indoor oxygen, dilute and discharge indoor carbon dioxide, formaldehyde and other pollutants, and maintain air quality.

[0037] Based on another aspect of the present application, the present application also provides an air conditioning system, wherein the air conditioning system has the ventilation assembly with variable air supply direction as above.

[0038] As configured above, the air in the air fan box 3 is pumped by the fan, in summer, the air temperature in the building outer area is high, the first air inlet pipe 2 is communicated with the second air outlet pipe 6 through the air fan box 3 to pump the air in the building outer area to the building inner area, so as to mix with the air in the building inner area, and then circulate to the outer area, forming the circulation of the air flow, reducing the heat in the building outer area, balancing the difference of the fresh air amount in the air in the building outer area and the building inner area, reducing the fresh air supply amount of the air conditioning box, and saving the energy consumption of the fresh air cooling; in winter, the air temperature in the building inner area is high, the second air inlet pipe 4 is communicated with the first air outlet pipe 7 through the air fan box 3 to pump the air in the building inner area to the building outer area, so as to mix with the air in the building outer area, and then circulate to the building inner area, forming the circulation of the air flow, which can reduce the heating amount of the air conditioner to the building outer area, balance the temperature of the building inner area and the building outer area, and save the heating energy consumption of the building outer area.
